Good points. I think you perfectly correct. I also think that starting low would be more logical than to assume one has a totally unproven, unevidenced 1200 rating upon signing on.
If you are stronger or really strong, you will still rise up from 600 in no time.
Ratings.... sorry....I was wondering if it wouldn't be more meaningful if once you register you start with a very very low rating, let's say 600 or whatever, so you have to make your way to your real game level. Sometimes you find some players which have 1300 but it's not real because they have just registered and won two games, or some other freeze that 1200 playing unrated forever. Anyway, 1200 is not a high rating but I was just wondering since I guess most of the chess community members must be around 1000 rating. Or maybe it would be kind of disencouraging to start so down, what do you think?
